CNC Gantry Machine

This is a 3-axis CNC gantry machine which has roughly 14" x 14" horizontal and 4" vertical movement.  It's an improvement from a previous design I had built.  The frame is designed using 1/2" thick medium density particle board, a driver board from HobbyCNC.com (PRO Drive), and using EMC2 for the controller.
